| Term | Definition |
|---|
| Cytoplasm | Area of cell from plasma membrane to nucleus(contain many complex structures) |
| Cytoplasmic Organelles | Membrane bound structures. Perform many of cell's complex functions |
| ER Network | A maze-like system of passages extending from the plasma membrane to the nucleus. Speeds movement of materials from cytoplasm to nucleus (e.g., RNA, nucleic acids, proteins, etc.). Site of synthesis of many important molecules. |
| Rough ER | Flattened, connected stacks surface covered with ribosomes, site of proten synthesis for golgi |
| Smooth ER | w/out ribosomes; network more tubular in appearance. Site of lipid synthesis |
| Golgi | Specific type of ER, highly comacted located near nucleus, recieves protiens and packages them in double membrane. completes final step. |
| Lysosomes | Vacuoles containing digestive enzymes |
| Endocytosis | the plasma membrane balloons inward and pinches off, trapping some extra-cellular substance |
| Phagocytosis | active form of endocytosis whereby the cell "engulfs' other microorganisms or large particles. |
| Centrioles | Resemble paired cylinders . contains 9 sets of microtubules with 3 microtubules per set. Each arranged perpendicular to the other. |
| Mitochondria | sasuage-shaped structures found through out the cytoplasm, double membrane, contains own DNA and own ribosomes. produce cells energy and convert to sugar and o2. |
| chloroplast | convert sunlight into energy, involved in photosynthesis |
| grana | contains chlorophylls(light trapping pigments) |
| Endosymbiosis | two cells coming together to function as one ex. mitochodria and chloroplast |
| Microfilaments | Envolved in endosytosis,cell internal transport such as vacuole movement and cytoplasmic streaming |
